DOOR HINGE.

Application filed August 31, 1928.

This invention relates to door and like hinges of the single pintle type, and this improvement has for its object lo provide a structural formation and combination of the hinge parts adapting the same for surface application to a door and door jamb, with the consequent avoidance of mortices or receiving recess for the leaf portions of the parts. rind further, to provide means whereby an effective bracing and reini'iorcing of the jamb member of the hinge is attained and its substantial attachment in place, is effected, all as Will hereina more fully appear.

ln the accompanying drawing:

Fig.. l, is a top View of the hinge parts in the preferred form of the invention, with portions of the door and door jamb shown in section..

Fig.'2, is a side elevation of the assembled hinge n'iembers.

Z5, is a front elevation of the same.

Like reference numerals indicate like parts in the different views.

ln this invention the door leaf or plate l,

and the jamb leaf or plate 2 are formed With' tubular pivot A`ars or knuckles 3, and l, through which the pivot pin or pin'tle 5 passes to pivetally connect said parts together, as lusual in the single pintlc type of door hinges.

The door leaf er plate l, is preferably of right angle shape comprising a narrow flange l carrying the pivot knuckles 3 of the leaf l, and a Wide flange l by W Lich the leaf 'l is secured to the surface of the dcor 6 by screws or like fastening means.

The door amb leaf or plate 2 of the hinge, in the present improvement, has its main portion of a thin plate formation formed with a longitudinal abutting shoulder or offset 7 a short distance from the pivot knuckles Il of the leaf or plate, With said shoulder or offset 7 formed by an added thickness in leaf er plate between said shoulder and said knuckles.

With the described formation, the shoulder or offset 7 is adapted to have abutting contact againstan edge or corner ef the door janib 8, with the thin main portion of the Serin No. 303,138.

leaf or plate resting against the surface of the side face of sai-d amb and secured thereto by screws or similar fastening means.

Another and material feature of the improvement, comprises an auxiliary leaf or plate 9 formed with knuckles l0 for engagement With the pivot pintle 5, and adapted to assume a right angle relation to the aforesaid jamb leaf or plate 2 and be secured to the surface of the casing 8 of the door jamb 8. lWith the described arrangement the auxiliary leaf or plate 9 forms a very effective brace for the aforesaid j amb leaf or plate 2, and strengthens the same in a substantial manner.

In the construction shown in the drawing, the auxiliary bracing leaf or plate 9, is formed as a part separate from the jamb leaf or plate 2 of the hinge, in that such formation is adapted to the manufacture of the hinge from sheet metal by suitable punch and die operations. It is however Within the scope of the invention to make said auxiliary bracing leaf 9, integrally with and a fixed part of the jamb leaf or plate 2, Where the structure is formed of cast metal.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is In a door or like hinge, a door leaf adapted for surface attachment to a face of the door and comprising a main attaching plate having angular end. extensions formed with pivot knuckles on their free ends, a door' )amb leaf having pivot knuckles and formed with a longitudinal abutment shoulder a short distance/from its pivot knuckles, an auxiliary bracing leaf having pivot knuckles in side relation to the body of the leaf, said bracing In testimony whereof I hereunto afliX my signature.
